Abstract

The present technology relates to an information processing apparatus, a method, and a program that can improve anonymity. An acquisition unit acquires a user identification ID that identifies a user and user data regarding the user. A derived ID generation unit carries out an operation using a one-way function, for data obtained from the user identification ID according to an increase in the number of the user data recorded in a recording unit, to generate a derived ID. A recording control unit causes the recording unit to record the generated derived ID and the acquired user data in association with each other to. In this way, the derived ID is generated according to the increase in the number of recorded user data, and the user data is recorded in association with the derived ID. Therefore, K-anonymity of the user data can be improved. The present technology can be applied to a server.

Claims

1. An information processing apparatus comprising:

an acquisition unit configured to acquire personal identification information that identifies a user and data to be recorded;

a derived identification information generation unit configured to generate derived identification information from the personal identification information on the basis of the number of already recorded recorded data; and

a recording control unit configured to control such that the derived identification information or the personal identification information, and the data to be recorded are recorded in association with each other.

2. The information processing apparatus according to claim 1, wherein

the derived identification information generation unit generates the derived identification information by carrying out an operation using a one-way function for the personal identification information.

3. The information processing apparatus according to claim 1, wherein

the derived identification information generation unit generates the derived identification information from the already recorded recorded data and the personal identification information.

4. The information processing apparatus according to claim 1, wherein

the derived identification information generation unit generates new derived identification information every time a predetermined number of the data to be recorded is recorded as the recorded data.

5. The information processing apparatus according to claim 4, wherein

the predetermined number is changed according to the number of the recorded data.

6. The information processing apparatus according to claim 1, wherein

the recording control unit controls such that the data to be recorded are recorded in association with the personal identification information or the generated derived identification information on the basis of the number of the recorded data recorded in association with the generated derived identification information, and the number of the recorded data recorded in association with the personal identification information.

7. An information processing apparatus comprising:

an acquisition unit configured to acquire personal identification information that identifies a user and data to be recorded;

a derived identification information generation unit configured to generate derived identification information from the personal identification information on the basis of the data to be recorded; and

a recording control unit configured to control such that the derived identification information or the personal identification information, and the data to be recorded are recorded in association with each other.

8. The information processing apparatus according to claim 7, wherein

the derived identification information generation unit generates the derived identification information from already recorded recorded data and the personal identification information.

9. The information processing apparatus according to claim 8, wherein

the derived identification information generation unit generates the derived identification information by carrying out an operation using a one-way function for data obtained from the most recently recorded recorded data and the personal identification information.

10. The information processing apparatus according to claim 7, wherein

the derived identification information generation unit generates the derived identification information on the basis of a type or recording date and time of the data to be recorded.

11. The information processing apparatus according to claim 7, wherein

the derived identification information generation unit generates the derived identification information in a case where the data to be recorded acquired from the acquisition unit is different from predetermined data to be recorded.

12. The information processing apparatus according to claim 7, wherein

the recording control unit controls such that the data to be recorded are recorded in association with the personal identification information or the derived identification information on the basis of the data to be recorded.
